A French flag flutters while smoke billows from burning shelters set on fire by migrants in the makeshift migrant camp known as "the jungle" near Calais, northern France, Wednesday, Oct. 26, 2016.

The number of migrants sleeping rough on the streets of Paris has risen by at least a third since the start of the week when the "Jungle" shanty town in Calais was evacuated, NBC News reported.

Along the bustling boulevards and a canal in a northeastern corner of Paris, hundreds of tents have been pitched by migrants — mostly Africans who say they are from Sudan — with cardboard on the ground to try and insulate them from the cold.
